As per my well calculated guess one GB of data transfer on Airtel's 3G network will cost not less than 999/-. Anybody who thinks Airtel, being the greedy behemoth it has grown into, will give us 3G speed of over 3Mbps with unlimited transfer for anything less than 3000 Rs is plainly day dreaming. (oh yeah, then there is always this 'fair usage' thing after 50GB)
